Abstract: A sensor is disclosed. The sensor according to an embodiment of the present invention may include a substrate; a first electrode pattern disposed on one side of the substrate to form a layer; a second electrode pattern disposed on the one side of the substrate to form a layer and separated from the first electrode pattern; a sensing layer located on the one side of the substrate and covering the first electrode pattern and the second electrode pattern and containing a semiconductor; a protective layer located on the one side of the substrate and covering at least a part of the sensing layer, and containing a material different from that of the sensing layer; a first electrode pad disposed on the one side of the substrate to form a layer and electrically connected to the first electrode pattern; a second electrode pad disposed on the one side of the substrate and electrically connected to the second electrode pattern; and a housing accommodating the substrate and including a filter spaced apart from the substrate, wherein the substrate includes an opening formed adjacent to an outer boundary of the first and second electrode patterns.

Abstract: An X-ray imaging apparatus includes an X-ray generator including a plurality of X-ray sources, an X-ray detector configured to detect X-rays radiated from the plurality of X-ray sources and generate a plurality of pieces of projection data, and a processor configured to apply log projection to each of the plurality of pieces of projection data, to apply weighted projection to the log-projected projection data, to apply a bidirectional ramp filter to the weighted-projected projection data, and to generate a tomographic image reconstructed based on each of the projection data to which the bidirectional ramp filter is applied.
